Description

Detailed Description of the Invention "Industrial Application Field" The present invention is designed to roughly sort out impurities mixed into the grain before it is fed to the threshing machine. This invention relates to a self-help control device for a coarse sorter.

``Prior art'' A pair of shakers are used to support the sorting sieve R in an inclined manner at the sink end, while the grains are flowing down from the inclined upper end of the shaking sorting sieve to the inclined lower end. There is a means to allow only the grains to leak through the sieve body and to allow the impurities to flow down to the slanted lower end side of the sieve body to roughly separate the grains and impurities.

``Problem to be Solved by the Invention'' In the method of refusal, when there is a change in the variety of grain, growth conditions, moisture content, etc., there is a problem in which there is no basis in the roughly selected sand grains or impurities. There was a problem that foreign matter or grains were mixed in more than I-.

``Means for Solving Problem R'' Therefore, the present invention provides a method for adjusting the coarse selection amount adjusting member of the rough separator based on the increase/decrease in the mixing ratio of sand grains or impurities in the coarsely sorted material sorted by the rough separator. It is constructed so that the mixing ratio r of grains or impurities in the coarsely sorted material is maintained constant through variable control as appropriate.

"Function" According to the present invention, even if there is a change in the grain variety, growth conditions, moisture content, etc., the impurity film mixed in the coarsely selected grains or impurities can be removed. This makes it possible to keep the ratio of mixed grains constant at all times, thereby reducing loss of general grains and maintaining accuracy in sand grain sorting.

The wooden embodiment is constructed as shown below, and the paddy supplied to the hopper (2), the supply valve (31) and the sieve body (61) flows from its sloping upper end S to its lower end. As the oscillation interlocks with the 1, only the paddy is sieved and sorted through the leakage hole (71) and falls, and at the same time, the impurity discharge port 1:a, l:h at the lower end of this slope, such as straw waste and some splinters, etc. The foreign matter falls. Then, the foreign matter that has fallen from the i-input discharge port (321) is supplied to the handling cylinder (331) through the guide gutter (30) and the input port +3112, and the rice grains and rice mixed in the foreign matter are removed. The paddy whose branches and stems have been removed by the re-threshing process of the handling barrel (33) falls downward from the crimp net 135171, and the remaining impurities removed from the paddy are discharged to the outside of the machine through the dust outlet (371). During the refusal operation, the amount of paddy leaking from the crimp net tunnel is detected by the sensor (38), and when it is detected that the amount of paddy is greater than the reference amount, the motor (4)
Adjust the supply valve (31) in the closing direction to reduce the supply amount, improve the screening accuracy of the sieve (61T),
The amount of paddy leaking from Crimp City A1351 will be reduced. On the contrary, when the sensor (38) detects that the amount of paddy is below the standard, the supply valve (3) is adjusted in the opening direction to increase the supply amount.
As a result of the increase in jl, the amount of paddy mixed in the impurities discharged from the outlet (321) is also added, and the crimp group +3

Based on the increase/decrease in the proportion of grains or impurities in the coarsely sorted material, the rough sorting amount adjusting member f41 (161f2212) of the coarse sorter is controlled, and the amount of grains in the coarsely sorted material is controlled. Or, the ratio of contaminants mixed in must be kept constant (even if there are changes in the variety of grains, the condition of the grain, or the moisture content)! ! ! Even under different conditions, what is the ratio of coarsely selected grains or impurities to impurities or sand grains mixed in with them? By keeping the grain constant at all times, it is possible to prevent grain loss from increasing and the sorting accuracy from decreasing, thereby improving the efficiency of this rough sorting process.
